Spring Sting

Believe it or not the first day of spring was today. I know it was hard to tell with the snow mixed with rain. Although yesterday it was sunny while the snow fell. So that has to be the sign that spring is here. Well another good barometer for judging the arrival of spring is the germination of annual plants. Stinging Nettle is one that we have a lot of during the season along the border of the golf course.

Stinging Nettle seems to be everywhere. The plant is apparent in fertile soils that have been recently disturbed. Makes pretty good sense. When the golf course was built there was some good amount of disturbance along the border of the golf course along along the wooded areas. It seems to be like a wall of Nettles in some places. Since we have done a lot of storm clean up along the border of the course, the additional disturbance I felt would produce a generous crop of the nettles.

This spring we are trying to act while the plant is young and control the weed with a selective herbicide to give us some relief. If the plant rubs against your skin most people feel a stinging sensation that becomes very itchy later. This is not an ideal situation for a golfer that would like to look for a shot that rolls just off the border of the turf. We are trying to act early to catch the plant young and also avoid the time at which new leaves begin to start on the shadowing trees.

If you have any questions about our weed control strategy or if you have any comments about the course please feel free to contact me.

Frost on the Pumpkin

I worked at a club a few years back in Sun City and the Pro, Tom would call me up in the mornings when it would actually get to freezing and say, "There's a little frost on the pumpkin, huh."  I always think of that saying as the weather begins to get a little colder.

During the times of cold winter weather we will need to delay traffic on the turf until frost is melted. We want to avoid frost damage, because recovery is very slow this time of year. Damage from a cart or a walker can take weeks to recover. The damage will start out purple in color and turn to a straw brown as the leaves begin to dry.

I like to use the analogy of a piece of glass shattering, when I explain frost damage. When the leaf blade of the plant is frozen and becomes crushed by a tire or a shoe it is basically like a piece of glass shattering into many pieces. Microscopically when the leaf blade sustains the damage the cells shatters into pieces. The pieces move through the plant destroying cells in its path. Once the plant begins to thaw the plant fluid leaks out and the leaf blade and will look water soaked and purple. This is the grass basically bleeding out.  The leaf blade is now dead and will turn brown. Rarely does this damage affect the crown of the plant so the plant itself is not dead. The problem is that growth is slowed during cold weather, which makes for a slow and painstaking recovery.

With that being said with my turf nerdy twang, we ask that walkers and cart traffic avoid turf while it is frozen to protect the grass. If there are any questions about frost and how we make the decision to delay golf please contact me.
